A new Canon patent for telephoto lenses with built-in teleconverter. For what mount? RF mount.…
And yet another Canon patent application for an RF mount lens. A new macro lens might be in the works.
Canon patent application 2022-16822 discusses optical formulas for a RF 100mm f/2 Macro lens.
PROBLEM TO BE SOLVED: To provide an optical system which is small in size, suppresses aberration fluctuation due to focusing, and can obtain high optical performance over an entire object distance from infinity to a close distance, and an image pickup apparatus having the same.
A macro lens whose main purpose is to shoot a short-range object is configured to be capable of shooting from an infinite object having a shooting magnification of 0 times to a short-range object having a shooting magnification of about 1x. desirable. Further, the macro lens is required to have low aberration fluctuation and high optical performance over the entire object distance at the time of focusing, and the focus lens group is small and lightweight in order to perform focusing at high speed. When the inner focus method and the floating method are used, it becomes easy to perform focusing at high speed, reduce aberration fluctuations due to focusing, and obtain high optical performance over all object distances from infinity to close range.
